	cygwin         : ChangeLog dtable.h 

Log message:
	Introduce device class to cygwin throughout.  Rename FH_DISK to FH_FS
	* (dll_crt0_1): Initialize device globals via device::init.
	* (dtable::init_std_file_from_handle): Use device numbers rather than
	names when they are known.  Should speed up process startup slightly.
	(dtable::build_fhandler_from_name): Pass path_conv device to build_fhandler.
	(dtable::build_fhandler): Accept device argument rather than separate
	device/unit arguments.
	(dtable::build_fhandler): Ditto.  Separate switch statement by devices which
	take units and those which don't.  Build unix/win32 names from device if
	(dtable::dup_worker): Reflect changes to build_fhandler arguments.
	* dtable.h (dtable::build_fhandler): Ditto.
	* (fhandler_base::set_name): Eliminate unit argument.  Use get_unit
	to derive unit.
	* fhandler.h: Separate FH device defines into devices.h include.  Define
	is_slow as appropriate for each fhandler_class.
	(fhandler_base::dev): New element.
	(fhandler_base::fhandler_base): Eliminate unit argument.
	(fhandler_base::get_device): Return device number.
	(fhandler_base::get_major): Return device major number.
	(fhandler_base::get_minor): Return device minor number.
	(fhandler_base::get_unit): Ditto.
	(fhandler_base::get_native_name): Return device format field.
	(fhandler_fifo): New class.
	(select_stuff::device_specific): Remove array.
	(select_stuff::device_specific_pipe): New class element.
	(select_stuff::device_specific_socket): New class element.
	(select_stuff::device_specific_serial): New class element.
	(select_stuff::select_stuff): Initialize new elements.
	* (fhandler_cygdrive::fhandler_cygdrive): Remove unit
	* (fhandler_tty_master::init_console): Use "console_dev" global
	to initialize captive console used by tty master.
	* (mmap_record::devtype_): Remove.
	(mmap_record::dev): New.
	(mmap_record::mmap_record): Use dev.
	(mmap_record::get_device): Implement via dev.
	* (fdsock): Use socket_dev global to initialize socket fhandler.
	* (path_conv::check): Accommodate new path_conv::dev element.
	(get_devn): Eliminate.
	(get_raw_device_number): Ditto.
	(get_device_number): Ditto.
	(win32_device_name): Accept dev argument.  Use it.  Use device::parse to derive
	potential device name.
	(mount_info::conv_to_win32_path): Accept dev argument.  Use it.
	* path.h (path_conv::devn): Eliminate.
	(path_conv::unit): Ditto.
	(path_conv::dev): Declare.
	(path_conv::path_conv): Don't initialize deleted members.
	(path_conv::is_device): Implement via dev element.
	(path_conv::get_devn): Ditto.
	(path_conv::get_unitn): Ditto.
	* (make_pipe): Use pipe[rw]_dev in fhandler construction.
	* Use new device_specific_* select class elements
	* shared_info.h (CURR_MOUNT_MAGIC): Update.
	(mount_info::conv_to_win32_path): Reflect new arguments.
	* (fstat64): Just use get_device() without interpretation for
	st_dev element.
	(stat_worker): Ditto.
	* (create_tty_master): Use ttym_dev in fhandler constructor.
	(tty::common_init): Check for tty major device number rather than FH_TTYM.
